I'm working on my own X11-based widget library because ...that's what I do in my free time. For that reason, the entire code dump of https://www.libcxx.org/w/ is not likely to work here. I was just hoping anyone would know off the top of their head of any other reason I might get a BadAccess response to a GrabButton, other than the only reason described in the X11 specs. The only reason I could find there was a conflicting grab, but according to x11trace I was ungrabbing the button before grabbing it again. In the meantime, for other reasons I had to reorder some of the event handling in my library, and that made the error disappear. From what I can tell, this sequence of events is identical: 000:<:0533: 24: Request(28): GrabButton owner-events=false(0x00) grab-window=0x03200003 event-mask=ButtonPress,ButtonRelease,EnterWindow,LeaveWindow,PointerMotion pointer-mode=Synchronous(0x00) keyboard-mode=Synchronous(0x00) confine-to=None(0x00000000) cursor=None(0x00000000) button=any button(0x00) modifiers=AnyModifier 000:<:06a7: 24: Request(28): GrabButton owner-events=false(0x00) grab-window=0x0320004d event-mask=ButtonPress,ButtonRelease,EnterWindow,LeaveWindow,PointerMotion pointer-mode=Synchronous(0x00) keyboard-mode=Synchronous(0x00) confine-to=None(0x00000000) cursor=None(0x00000000) button=any button(0x00) modifiers=AnyModifier 000:<:06d8: 12: Request(29): UngrabButton button=any button(0x00) grab-window=0x0320004d modifiers=AnyModifier 000:<:09f3: 24: Request(28): GrabButton owner-events=false(0x00) grab-window=0x0320004d event-mask=ButtonPress,ButtonRelease,EnterWindow,LeaveWindow,PointerMotion pointer-mode=Synchronous(0x00) keyboard-mode=Synchronous(0x00) confine-to=None(0x00000000) cursor=None(0x00000000) button=any button(0x00) modifiers=AnyModifier 000:<:0a0a: 12: Request(29): UngrabButton button=any button(0x00) grab-window=0x0320004d modifiers=AnyModifier 000:<:0a0d: 12: Request(29): UngrabButton button=any button(0x00) grab-window=0x03200003 modifiers=AnyModifier For grab-window=0x0320004d there's a grab, an ungrab, grab again, and ungrab. Same as last time. Although the other events are different, based on my read of the specs only other grabs should matter here, and nothing else. _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
